Tracked down this one:

File http://www.evilla.com/html/about/index.html - Line 149 :
  <tr class="White">

But in

http://www.evilla.com/html/includes/cssbin/sitestyle_ie.css - Line 97 :  .white {
    background-color:#ffffff
  }
So the problem is : Mozilla is case-sensitive, IE is not.
I don't know the CSS-definition exactly enough, maybe it's an evangelism, maybe
it's a bug.

Excerpt from CSS2 ( http://www.w3.org/TR/REC-CSS2/css2.txt )

     All CSS style sheets are case-insensitive, except for parts that are
     not under the control of CSS. For example, the case-sensitivity of
     values of the HTML attributes "id" and "class", of font names, and of
     URIs lies outside the scope of this specification. Note in particular
     that element names are case-insensitive in HTML, but case-sensitive in
     XML.

The same with CSS1. It's a bug.

[Eric A. Meyer (dead account)]

Actually, it's not a bug, since class and ID names are case-sensitive according
to HTML 4.01, and Mozilla honors that.  However, I think Mozilla ought to be
case-insensitive about class and ID names in Quirks mode in order to conform
with legacy (mis)implementations.
